Whirlpool MicrowaveÂ Repair
Lightning sparks can be seen inside my microwave oven when it is operating
Sparks, or arcing, inside your Whirlpool microwave oven occurs when food or liquid is left in the cavity or on the wave guide cover of your unit.
If the wave guide on your microwave has any burn spots, it is best to clean your microwave unit well.
If the cavity on your microwave unit has any burn spots, spot sand it to a smooth finish and touch it up with microwave interior paint.
Please note that if there are any burn holes in the cavity of your unit, do not use the unit. Seek professional help from a qualified appliance repair technician in completing this Whirlpool microwave repair.

Over the range microwave door stuck shut
More than likely you've just got something that's possibly broken internally in the microwave. There are a lot of little plastic pieces that make up the door locking mechanism. It's possible that one of them has snapped off and causing it not to close all the way. It could be that it's just a simple door adjustment.
